Subject[PATCH 10/38] perf tools: Pass session arg to perf_event__preprocess_sample()
Date
The perf_event__preprocess_sample() translates a given ip into a
matching symbol. To do that, it first finds a corresponding thread
and map in the current thread tree. But for indexed data files, it
needs to find a thread (and map) with slightly different APIs using
timestamp. So it needs a way to know whether this session deals with
an indexed data file or not.
